v1.12.8

2025-05-08

Rollbacked JS to es11 for wider compatibility.

v1.12.7

2025-05-03

Fixed an issue that caused the chat to block clicks if Floating Chat is enabled, even if the chat is collapsed and not visible.
Fixed floating not being styled correctly if a new video with a different chat availability loads without leaving fullscreen mode.
Fixed and issue that caused the chat to sometimes clip behind the headmast.
Styled the float chat drag bar cursor to be move instead of default.

v1.12.6

2025-04-27

Fixed version warning. The shown flag was not being loaded from storage.

v1.12.5

2025-04-27

Changed script to no longer run in iFrames. The YouTube minions seem to have finally realized that they were unnecessarily stacking border styles on their chat elements. My fix that previously ran in the chat iFrame is no longer needed.

v1.12.4

2025-04-26

Changed Tampermonkey verion warning to once per lifetime. (was once per update)

v1.12.3.1

2025-04-24

Improved theater mode chat width scaling logic.
Fixed youtube secondary column being unintentionally scaled with the chat width.
Fixed youtube shorts thumbnails being unintentionally scaled with the chat width.
Fixed a few minor style issues that would occur if the chat style has been toggle on then off.

v1.12.1

2025-04-23

Fixed chat border fix style were not being properly applied.
Fixed an issue that caused chat to be positioned incorrectly when switching into fullscreen mode.
Fixed theather mode chat width to be occasionally calculated incorrectly when resizing browser window.

v1.12

2025-04-19

Adds the ability for the chat width to be adjusted in theater mode. The current max is set to be 1/3 screen width; The minimum is set to 300px, reflecting YouTube's chat minimum. The limit could be changed in the future but I do not see the need for that.

There is currently a low impact bug with how floating chat is positioned when switching in and out fullscreen mode. This will be fixed in a future patch.

Fixed some bugs in the settings loading logic that previously made settings version-dependent. This likely caused little to no issues, as setting-related features had not changed for quite some time.

Fixed a bug where simple mode would run regardless of the script's activation state.

v1.9.3

Fix extra border in chat frame when chat is in replay mode.

v1.5.6

2025-01-12

v1.5.5

2025-01-12

Make video player fixes always apply. YouTube seems to still have rounding issues when trying to hide their video player during the end screen during certain zoom levels (on certain browsers only?), the script now shifts the video container up by 1 pixel to hide the rounding error without being noticable during regular video playback.

v1.5.4

2025-01-11

Changed the script to hide the chat in fullscreen mode until YouTube fixes their fullscreen issue. This mimics the old default behaviour of YouTube and is much easier than having to override YouTube's srubbing UI.

2025-01-10

Fixed an issue where going to the previous page would not trigger headmast width calculations if the previous page is the YouTube homepage.
